This device can't run the 3D version. Play the Classic version instead, your progress is the same.
Play ClassicEvery bite gives you more release power. More power = bigger poo = more coins. Better food unlocks in higher worlds.
Worlds cost coins. Every world gives a bigger coin multi and better food. You keep your worlds when you rebirth.
Rebirthing takes your coins and food back to zero, but every rebirth adds +1× to your food multi and your coin multi forever. You keep your worlds and Auto Poo.
Hold the PUSH button (or the screen, or the Space bar) and let go when the meter is in the gold zone for a PERFECT poo. Drag the 3D scene to spin the camera round, use the mouse wheel or pinch to zoom, or the arrow keys and Q / E. Same save as the Classic version.
